Hi.
Same case for me, my OH installations relies very much on GCE device IPX800, exactly I’ve three running fine the last 2 years over OH2.4.
I’ve made a couple of tests, one with manual configuration, the preferred for me, and the other one using the OH3 GUI. The first was impossible to configure properly, the second one was entirely configured using the GUI, but after a restart all the events at the ipx800 side are not reflected in OH3, but if the item bonded with the ipx800 channel is edited and saved (whitout any modification), the item start to refresh correctly until next reboot.
Thanks a lot for your work, i’m willing to help in order to solve this matter.
